Required:

If a students at random, find the probability the students the student is a senior

Explanation:

To do this , we calculate the total students

Total=4+6+2+2+3+4+6+3

Total=30

next select the value in the cell that intersects senior

male + female=2+3=5

Hence, the probability is

[tex]\begin{gathered} Pr=\frac{senior}{total} \\ \\ Pr=\frac{5}{30} \\ \\ Pr=0.3333 \end{gathered}[/tex]

Express as percentage

[tex]\begin{gathered} Pr=0.3333\times100\% \\ Pr=33\% \end{gathered}[/tex]

Required answer:

30%
